Sourced from ijson's changelog.

[3.4.0]

• Added support for PEP 489 multi-phase initialisation and per-module state for our C extension, allowing us to support sub-interpreters with per-interpreter GIL.
• Advertise support for free-threading python mode.
• Removed support for Python < 3.9.
• Enhanced generators so they yield all possible results to users before errors are raised (#123).
• Added ijson.ALL_BACKENDS constant listing all supported backends (which might or not be available at runtime).
• Added a capabilities constant to each backend describing which capabilities it supports.
• Exposing backend's name under <backend>.backend_name, and default backend's name under ijson.backend_name. This is similar to the already existing name constant, only slightly better named to hopefully avoid confusion.
• Restructured source code so all code lives under src/, and the ijson.backends._yajl2 extension under src/ijson/backends/ext/_yajl2. This allows C backend tests to actually run on cibuildwheel.
• Improved performance of parse routine in C backend by ~4%.
• Fixed several potential stability issues in C backend around correct error handling.
• Fixed corner-case wrong behaviour of yajl2_c backend, which didn't work correctly with user-provided event names.
• Pointing to our own fork of yajl (for when we build it ourselves) that contains fixes for all known CVEs (#126).
• Removed leftover compatibility bits in the C backend.
• Fixed potential issue with yajl and yajl2 backends where crashes could occur at interpreter shutdown.
• Removed tox.
• Moved static project metadata to pyproject.toml.
